-My present invention relates to an imroved dust separator' particularly adapted of which the ,followinga or use insuction cleaningmachines. In

to draw air from va dust separating device, and th'ewithdrawal' of this air from the separator'causesother air to'rush 'into the separator through a suitable clean# ing 'nozzle and tubular-connections, bringing with it dust picked up at the the same in the separator. The` best resu ts` are securedb causing. a

.large volume of air to pass, an it is therefore `desirable to secure a .'-large straining surface in the dust separatonlso as to ob? struct as little as possible the passage of To the attainment of this desirable characwill hereinafter become apparent, my invention consists of certain constructions and combinations of parts which will now be .describedin 'connectionwith the accolnp'ag of the saine,

This hose is vattached ,to the cleaning nozzle and brings air with its suspended the air to the interior of a drum or frame .11, formed of Woven wire cloth or other oraminous' material, and of. somewhat less diameter than the drum .Patented Feb .1 1910'.

andthe head; 5 may dust to the separator. vThis nipple 9 is so placed that it conducts 3. This framejll-is attached to the head by ineansofa flange ring 12, this ring proj ectinga short distance from the heu-d 5 for a purpose which will be later described'. The frame l1 is supported in the horizontal position by nieans of afg bracket or support 13, carried in the drum 3.

V This bracket 13 is desirable -to properl -po- .80

sition the fram'eand to remove any ten ency toward lc'ilmge at 'the gasket 6, but is not es' lsential to a successful operation of the device. Closely enveloping the frame 11 is a 'straining bag 14 of any Vcloth suitable to strain tine dust out of the air, for'instance 'unbleached cotton or the like.y This bacr is of tubular form, open at both ends, andjo slightly greater length than the frame 11. It is attached to this fra-me by binding it tightly around the flange or'elastic 18 or the equivalent. The

etween the bag and the yhead 5 so that there ring l2 with cord shall be no leakage of air past the lend-of the-bag l 'adjacentto the head, [as would be. thecase were the ring 12 notused.; .heppposite end'- il ter, by acord 15 tied-a manner access xnayrbelhadtm rator diium 3 from thebottom' and rises point nea-r the to of the drum. The purpose of this is to insure the retention in' the bottom of the driim cfa-ny dust which might pass' throu h the straining bag. l I have escribed Vhis separator as-ir'i'terposedbetween the cleaning nozzle and the pumping mechanism, and this is for the purpose of removing thedustl from the air before it enters the pumpinfr device, butin "cases where the passage of dust vthrough the pumpingdevice'would not be objectionable, the dust separator would operate in the same manner were it attached to the exhaust ofthe pumping de'vice and used merel to remove the dust; from the air before re easuntying the cord 15 and opening the end of end of'sa-id bag to facilitate hei'emoval :of

ing the latter inthe room`. A It isl also obvious that diierent means for'attaching the head 5 to the drum 3 might be used,'.'but L preferl the construction illustrated and described.

The operation of the device is as follows: Air entering the drum. through Athe pipe 10 and' pple 9 is discharged within theframe 411 and straining lbag 14. It then .passes through this frame and bag, the dustbeing retained by meshes of the latter and enters Vthe annularspace-jwithin the drumB, surrounding the bag.' Any dust 'which-ma'y have passed through the baggvill b e precipitated in thedriim and the air then completely relieved of its dustwill pass out bythe, pipe 16. Tol clean the device, the p`ipe 10 is disconnected' and the. springs 7 are swung toi the sides. The head with -its at-k tached frame and bag aretheii withdrawn. This may be takento any. convenient place land the dustl contained be emptied out .by

the bag. .Whatever dust has passed through the straining cloth and been deposited in Vthe bottom of the drumB may be removedthrougl 'the .end of the drum, but it has been foundf that practically no dust passes i `through vthe cloth and such cleaning is rarely necessary. f r f I 'am aware Vthat the idea of depositinginside a straining bag-'dirt carried there by air is old, and do not broadly claim that'.

idea, but the idea of -distending said bag by 'a frame to securefull use of" the surface of the bag and ofproviding an opening in the the collected dirt without'i'emoving the bag from the frame, forms a radical improvement over the volder methods and greatly increases the etiiciency and ease of 'operation. It will be noted thattlie straining bag -is removed from the drum without untyingr anyfstrings oi even touching the bag andI without danger ofspilling any dirt during the operation. After Athe end has been opened the collected dust may be taken out without beating the bag'and. without unnecessary handling of thesame. It is thus a relatively simpleand clcanoperation to remove dust space available 'Withoutdeparting from the y ge'neral'spirit' of the invention.
